Extended triggered position method and device

Abstract

An extended triggered location method and device is provided. The device includes the following: a location calculating unit to calculate location of the target terminal and determine the location information, and a third party location reporting unit to send the location information of the target terminal to the third party terminal periodically or only when the area triggered condition is sufficed. With the present invention, the third party terminal can obtain the location information of the target terminal periodically or receive the notice of the target terminal's entry into / exit from a target area, in accordance with the principles of periodical location or area trigger location. Thereby, the invention supplies new location service application and satisfies the subscriber's demand for different location service applications.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation of International Patent Application No. PCT / CN2007 / 000875, filed Mar. 19, 2007, which claims priority to Chinese Patent Application No. 200610065534.8, filed Mar. 20, 2006, each of which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to the technical field of user plane-based mobile location service, and particularly, to an extended triggered location method and device.BACKGROUND OF THE INVENTION[0003]Secure User Plane Location (SUPL) is a user plane-based standard protocol, which is a communication protocol allowing a mobile phone user to communicate with a location server, e.g. SUPL Location Platform (SLP), to obtain the location of a mobile location SET.[0004]Generally, immediate SET location includes network-initiated location and SET-initiated location. Specifically, the network-initiated location refers to that a location request initiat...

AI Technical Summary

Benefits of technology

[0023]The embodiments of the present invention provide a triggered location method, which solves the problem that the location result cannot be sent to a third party periodically, according to a request of the target SET or network or cannot be sent to the third party when a certain area event triggering condition is met, and thereby provide a variety of location result notification mechanisms for triggered location and enrich the applications of location services.

[0024]The embodiments of the present invention provide a triggered location device, so as to enable a third party SET to obtain the location information of the target SET periodically in the case of periodical location or area event triggered location, and thereby meet the users' demands for different location service applications.

[0031]It can be seen from above technical solutions provided in the present invention that in the embodiments of the present invention, the function of transmitting the location information to the third party that is supported in the immediate location procedure is introduced into the triggered location procedure. The third party SET that needs the location notification is pre-configured, and upon the request from the target SET or network, the location information is sent to the third party periodically or only when a certain area event triggering condition is met. In this way, the location platform may ensure that in the case of periodical location, the third party SET can receive the location result notification of the target SET periodically in case of emergency, and in the case of area event triggered location, area event monitoring tasks can be set for different SETs of different persons so that when the area event triggering condition is met, the persons responsible for a monitoring task can receive the triggering notification and the location information of the monitored object. The present invention enriches the applications of location services and can meet the demands of different users in a better way.

Problems solved by technology

However, the protocol currently doesn't support sending the location result periodically to the third party according to a request of the target SET or network or sending the location result to the third party only when a certain area event triggering condition is met.
